PTI Transformers is one of North America’s leading manufacturers of transformer technology. Our two facilities, located in Winnipeg, MB and Regina, SK, can produce transformers up to 600MVA and 525kV.

All transformer design and engineering is completed in-house and our decades of experience help us to provide solutions that meet and exceed the most stringent customer specifications. PTI Transformers uses numerous software applications to verify the designs and simulate field conditions, such as:

Short circuit capability
Design performance (losses, impedance, temperature gradients, sound level)
Impulse voltage
2D electrical & magnetic fields
3D electric field
Electromagnetic transients
3D mechanical design and modeling

Each transformer is rigorously inspected throughout the manufacturing process using mature practices and modern equipment. Every transformer is also tested using state-of-the-art equipment, to verify design criteria, customer requirements, and industry standards, including:

Low voltage testing
High-voltage dielectric testing
Transformer performance and design verification (loss measurement, impedance, etc.)
Thermal performance (temperature rise/heat run)
Sound level
Sweep Frequency Response Analysis (SFRA)
Control and functional testing

Our commitment to quality, safety and customer satisfaction gives customers confidence they made the right decision to choose PTI Transformers.
